There are two issues with Jazz that papul1993 has mentioned - future price of petrol & diesel and availability of honda network. First diesel prices- I think that after roll out of Aadhaar (UID) to a major portion of population, govt will start providing cash subsidy to farmers for the diesel. This may likely to happen in the next 4-5 years. Once it happens, diesel prices will rise considerably in comparision with petrol prices.
Secondly, with Jazz becoming popular and with the launch of Brio, Honda network is bound to expand quite significantly in every part of country. Moreover, people becoming quality conscious, Honda (without any doubt known for quality products) will gain more and more customers meaning demand for more and more service centres.
So, future for Jazz is nothing but bright.
You can try asking for floor mats , mudflaps , seat covers , undr body anti-rust coating , sunfilm , car body cover etc.
Mudflaps are standard accessory across all varients.
